Top 20 Call Center Companies in the US for 2027

Providing excellent customer service through the phone is essential for building customer loyalty and keeping your business competitive. But running an in-house call center comes with significant costs, from hiring and training agents to managing technology, quality assurance, and day-to-day operations.

Outsourcing is one way to reduce that burden. A business process outsourcing provider can give you access to trained agents, established support infrastructure, and flexible staffing without the overhead of building an entire operation yourself.

The challenge lies in finding the right partner. Hundreds of call center outsourcing companies operate in the US market, and on paper, many offer similar services, impressive capabilities, and promises of high-quality support. How do you separate the providers that can actually deliver from those that simply look good on a website?

We’ve done the legwork for you. This guide compares the 20 best call center outsourcing companies in the US, with a breakdown of their services, delivery locations, customer ratings, and key strengths. You’ll also find our ranking methodology, typical pricing models, guidance on choosing a provider for your business, and practical tips for evaluating potential partners before you commit.

Why Outsource a Call Center?

In a crowded market, businesses need more than competitive prices and quality products to stand out. The customer experience plays a major role in whether people return or take their business elsewhere. Research from the Qualtrics XM Institute estimates that poor customer experiences put nearly $3 trillion in global sales at risk, based on a survey of more than 20,000 consumers across 14 countries.

Customer support is a big part of that experience. Responsive, helpful service can strengthen customer loyalty, generate positive reviews, and support long-term growth. Poor service, on the other hand, drives customers away. But building an in-house support team takes time and money, from recruiting and training agents to managing daily operations. Outsourcing offers another option, allowing businesses to improve customer experience without building an entire department from scratch.

A reliable outsourced call center can handle phone, chat, and email support while giving your business room to focus on its core operations. The challenge is finding a provider that fits your needs, budget, and service standards. Choosing the right partner can help you deliver better customer service, streamline operations, and support business growth.

What Do Call Center Outsourcing Companies Do Today?

Call center outsourcing is changing quite quickly. The old model was simple: a company moved calls to an external team to add capacity or reduce costs. That still happens, but it is becoming only one part of the picture.

Today, outsourcing providers are increasingly expected to help run and improve the customer operation itself. That includes bringing together channels, introducing automation, handling more specialized work, and taking responsibility for measurable service outcomes rather than simply supplying a certain number of agents.

AI is moving into the operation

AI is the most obvious change, but the interesting part is where it is being used. It is working behind the scenes: summarizing calls, searching knowledge bases for agents, reviewing conversations for quality, forecasting demand, detecting intent, and taking repetitive administrative work away from frontline teams. More advanced systems are starting to handle entire simple requests without an agent.

Investment is accelerating fast. Gartner found that customer service leaders increased AI spending by 38% in 2026, while their overall service budgets grew by just 2%. At the same time, Gartner warns that an entirely agentless contact center is neither the most likely nor the most desirable outcome. Gartner’s 2026 research shows where the market is heading: more automation, but not necessarily fewer humans everywhere.

The work is becoming more specialized

As simple interactions become easier to automate, the work left for human teams is getting harder. That means outsourcing providers are increasingly handling technical support, regulated customer service, fraud and risk operations, complex billing issues, retention, and other situations where agents need product knowledge or judgment rather than a script.

This shift is important. Forrester argues that as automation makes routine work easier to replicate, industry expertise becomes more valuable, not less. Clients increasingly want providers that understand the specific rules and operating realities of sectors such as healthcare, banking, insurance, or technology. Forrester’s 2026 BPO analysis describes this as one of the main changes reshaping outsourcing.

Omnichannel now means keeping the context

Phone is not disappearing. Neither are chat, email, messaging, or self-service. The real challenge is making them behave like one service rather than separate departments. A customer may start with AI self-service, move to chat, and eventually call an agent. They should not have to explain the same problem three times. That sounds obvious, but connecting customer history, data, tools, and handoffs across channels remains one of the harder parts of modern contact center operations. The trend is therefore moving away from simply offering more channels toward managing the whole conversation across them.

Human agents are moving toward harder work

There has been plenty of discussion about AI replacing contact center jobs, but the picture in 2027 is more mixed. Gartner found that 85% of service and support leaders are expanding agent responsibilities as AI takes over simpler work, while 31% reported implemented or planned AI-related frontline workforce reductions through early 2027. The research suggests that the role is changing faster than it is disappearing. Agents are left with the cases where context, judgment, negotiation, or empathy matter. That also raises the bar for recruiting and training outsourced teams.

Companies are starting to buy outcomes, not only agent hours

This may be the less visible but more important change. Traditional outsourcing contracts were built around people: a certain number of FTEs, hours, or seats. AI makes that model harder to justify when part of the work can be automated.

Forrester says BPO is moving toward models where clients pay more attention to results such as faster resolution, higher CSAT, lower operating costs, or better collection rates rather than simply the amount of labor used. More than half of enterprise services decision-makers in its recent research already reported using outcome-based pricing in some form.

For companies choosing a call center partner, this changes what is worth comparing. Location and hourly rates still matter, but so do the provider’s ability to automate sensible parts of the operation, handle more complex work, preserve context across channels, and show that service is actually getting better.

Top 20 Contact Center Companies for 2027: Side by Side Comparison

Here are 20 best call center companies in the US and beyond:

How we chose and ranked these call center outsourcing providers

We started by identifying call center outsourcing providers that operate their own agent teams and serve US clients. To compare them consistently, we scored each company from 1 to 5 across six weighted criteria, using information we could verify on company websites, in corporate filings, or through major news outlets. If we couldn’t verify a claim, we treated it as missing rather than giving the provider credit for it.

Here’s what we evaluated and how much each criterion contributed to the final score:

• US delivery and coverage (25%): We looked at whether providers have a US headquarters, delivery sites in the country, or nearshore teams that operate in US time zones.
• Depth of call center services (20%): We assessed the range of services offered, including inbound and outbound support, technical support, omnichannel service, and AI-assisted operations.
• Verified security and compliance (20%): We checked for company-confirmed certifications and compliance standards, including ISO 27001, SOC 2, PCI DSS, HIPAA, and HITRUST.
• Scale and language coverage (15%): We compared workforce size, geographic reach, and the number of languages supported.
• Verified customer feedback (10%): We reviewed ratings on Clutch and Gartner Peer Insights, taking the number of reviews into account.
• Flexibility and pricing transparency (10%): We considered whether providers publish their rates, accept smaller teams, offer pilot programs, or provide month-to-month contracts.

Ties go to the provider with the higher US delivery score, followed by security, scale and language coverage, and service depth. The table below shows each company’s score across all six criteria, along with its weighted overall score.

How Much Do Call Center Outsourcing Companies Charge?

Most enterprise providers on this list offer custom quotes based on call volumes, support channels, operating hours, and language requirements. As a result, call center outsourcing costs can vary considerably between providers. A few companies publish their rates, giving you a starting point for comparing options before requesting quotes.

Several factors influence the final price. Offshore agents generally cost less than onshore or nearshore teams, while specialized or regulated support tends to cost more than general customer service. Round-the-clock coverage and multilingual requirements can also increase costs because they require additional staffing.

To compare proposals fairly, give each shortlisted provider the same requirements, including expected volumes, channels, operating hours, languages, and service levels. You can also ask whether the provider offers outcome-based pricing tied to metrics such as resolution rates or customer satisfaction (CSAT).

Which Call Center Company Fits Your Situation?

Choosing a call center outsourcing provider starts with understanding what your business needs most, whether that’s compliance with industry regulations, coverage across multiple time zones, affordable staffing, or specialized technical support. The providers on this list vary in their delivery models, service offerings, and pricing, so the right fit depends on your operational requirements and budget. Use the guide below to identify which companies are worth shortlisting before you request proposals.

How to Choose the Right Call Center Provider

As a business owner, you should understand that your call center service provider becomes your brand ambassador. When selecting a call center vendor for your business, you are selecting a partner who will serve as the voice of your company and the impression you will make on your customers.

A call center that operates effectively has a dual role: providing excellent customer service while resolving tickets. To achieve success, it’s essential for call centers to understand their customers’ needs and promptly address them.

Look for exceptional service quality

Before outsourcing customer service, you need to ensure that the company provides high-quality service. A reputable call center company should have well-trained agents who can handle a variety of customer issues efficiently and professionally. Opt for an outsourcing provider with a solid reputation for delivering excellent customer service and a proven track record of meeting service-level agreements.

Check industry expertise

Find call centers with industry-specific experience that understand your unique needs and challenges. This serves as a guarantee that they can provide the best service possible and help you achieve your business goals. The largest call center outsourcing companies that have been listed above have solid experience in diverse industries, making them an ideal choice for businesses that require specialized expertise in their particular niche.

Opt for scalability and adaptability

Another important factor to consider in terms of call center outsourcing is whether call centers are scalable and adaptable enough for your changing business requirements. Your business demands can shift over time, and it’s important to know that your service provider can scale up or down as needed to meet your evolving requirements.

Examine technological capabilities

Look for call center companies that use advanced technologies such as artificial intelligence, chatbots, cloud-based solutions, and automation to enhance client service and optimize operations. Good call centers should have access to the latest technology and tools to help them provide the best service possible.

Match the delivery model to your customers

Before comparing prices, decide where your agents should be based. Onshore teams are often a good fit for complex, regulated, or high-value customer interactions that require close collaboration with your in-house staff. Nearshore teams in Latin America offer lower costs while maintaining substantial overlap with US business hours. Offshore teams can help you reduce costs further, handle large support volumes, and provide overnight coverage. The choice between nearshore and offshore call centers ultimately depends on your budget, time zone requirements, language needs, and the complexity of the work.

Ask for proof before signing a contract

Once you have a shortlist, look beyond sales presentations and verify that each provider can deliver what it promises. Ask for the following before committing to a contract:

• Certifications: Request current documentation for relevant standards, such as ISO 27001, SOC 2, PCI DSS, or HIPAA compliance, rather than relying on logos displayed on a website.

• Comparable references: Ask for two or three client references from your industry, ideally from businesses with similar support volumes and operational requirements.

• Quality metrics: Find out how the provider measures customer satisfaction (CSAT), first contact resolution, and quality assurance performance. Request recent results and ask how it addresses recurring issues.

• A pilot program: If possible, start with a 30- to 90-day pilot with clearly defined performance targets before committing to a long-term contract.

• Exit terms: Clarify notice periods, data handover procedures, and how the provider will handle trained agents and the transition of operations if you decide to leave.

Takeaways

Partnering with a reliable call center service provider is a perfect solution for those businesses seeking to boost efficiency, increase CSAT, and increase customer retention. Outsourcing customer service is a smart move, offering excellent service without the overhead costs of in-house staffing.

Still, it is essential to discuss all nuances and preferences before sealing any call center outsourcing contracts, as not all companies can cope with the tasks you need to be done. Keep in mind that customer service providers vary in their capabilities, with some only able to provide email support or phone support, and others capable of handling a wider range of channels and services.

To ensure a positive customer service experience, it’s crucial to select top call center outsourcing companies that can meet your specific needs.
